That's actually a great idea, and I may choose to implement it. For this particula case, the issue relates to vBPager. Wven when a person is on Ignore, they can still IM/Page the person. I want to "disappear" the vBPager icon if the intended recipient has the person on Ignore, so they won't be bothered.
I will have look at it this afternoon and post you the code to do what you want sometime this evening!
